I don’t know what to put on “METHOD” and “EXPLANATION.”
Please help me! :-(
I would choose "Elimination" method.
Explanation:Elimination is the easiest method to solve an equation. Because in this method first we have to find the value of "y" by eliminating "x". And at last,the value of "y" which we have got by elimimating,we need put to any equation as we desire. And finally the equation will be solved.

A group of 8 friends arrive at a party.
They increase numbers by 20%. How
many people now at the party?
The number of people at the party now is 23.
The percentage of a number is the fraction of that number multiplied by 100. Percentages are represented with this sign: %.
3 friends arrive at a party. The percentage of people increase by 20%.This can be represented with this equation:
p x 20% = 3 people
where p is the number of people at the party before the friends arrived.
p = 3 / 20%
p = 3 / 0.20
p = 15 people
The total number of people at the party now : 15 + 8 = 23.

The green pyramid's square base has sides that are 14 centimeters long, and its volume is 21
times the volume of the orange pyramid. What is the height of the green pyramid?
The height of the green pyramid constructed by Natalie while playing with magnetic building tiles is 26.25 cm.
Volume of the orange pyramid
The volume of the orange pyramid is calculated as follows;
V = ¹/₃Ah
where;
A is the base area of the pyramidh is the height of the pyramidV = ¹/₃ x (7²) x 5
V = ¹/₃ x (245 cm³)
Volume of the green pyramidVoume = 21 x [¹/₃ x (245 cm³)]
Volume = 1,715 cm³
Height of the green pyramidV = ¹/₃Ah
3V = Ah
h = 3V/A

Describe the graph of the function.
y =Square root of
x-1 + 4
Answer: The answer is D. the last option
Step-by-step explanation:
The correct answer is option d) The graph is the radical function, y = √x shifted right 1 unit and up 4 units.
The original function is y = √(x - 1) + 4, which represents a radical function.
This function involves taking the square root of the quantity (x - 1) and then adding 4 to the result.
By shifting the function right 1 unit, we are replacing x with (x - 1). This means that the graph will be shifted horizontally by 1 unit to the right compared to the standard square root function.
By shifting the function up 4 units, we are adding 4 to the output of the square root function.
This means that the graph will be shifted vertically by 4 units compared to the standard square root function.
Therefore, the graph of the function y = √(x - 1) + 4 is the radical function y = √x shifted right 1 unit and up 4 units.

There are 750 toothpicks in a regular-size box. A jumbo-size box is made by doubling the length, width, and height of the regular box. How many toothpicks will the jumbo box hold?
2250 toothpicks
1500 toothpicks
3000 toothpicks
6000 toothpicks
Answer:
The last option: 6,000 toothpicks.
Step-by-step explanation:
The formula I used: (2L) (2W) (2H)
If a jumbo sized box is made by doubling the length, width, and height then each measurment will be doubled so length x2, width x2, height x2 so therefore those added up would be 8. Then just do 8 times the volume. 8 x 750 = 6,000.

Identify the asymptotes of the graph.
x = 2, y = 2
x = –2, y = 2
x = 2, y = –2
x = –2, y = –2
Answer:
A) x = 2, y = 2
Step-by-step explanation:
An asymptote of a curve is a line which the curve gets infinitely close to, but never touches.
From inspection of the graph, we can see there is a horizontal and a vertical asymptote, both indicated by the dashed straight lines.
The horizontal asymptote is y = 2 (blue dashed line)
The vertical asymptote is x = 2 (red dashed line)
Therefore, the asymptotes are: x = 2, y = 2

Step-by-step explanation:
Mia is designing a cake for a birthday party. She plans for a total of 12 guests, each of whom may eat a piece of cake that has a volume of 8 cubic inches. Which of the following cakes would provide enough cake for each guest to have one piece of cake, with the least amount left over?
Square cake: side = 8 in., height = 2 in.
Round cake: diameter = 6 in., height = 3 in.
Round cake: diameter = 8 in., height = 3 in.
Rectangular cake: length = 6 in., width = 9 in., height = 2 in.
The square cake can be distributed in such a way that each person out of 15 guest may get 8 [tex]inch^{3}[/tex], with the least amount left over .
The Correct option is (1).
What is Volume of any shape?The volume of an object is the amount of space occupied by the object or shape, which is in three-dimensional space. It is usually measured in terms of cubic units.
First find the volume of square cake,
Volume = l x b x h= 8 x 8 x 2
=128 [tex]inch^{3}[/tex]
Now there are total 15 guests, Each of get
=[tex]\frac{128}{15}[/tex]
= 8.533 [tex]inch^{3}[/tex]
2.Volume of round cake (d= 6 inch, r=3 inch, h= 3 inch)
Volume= [tex]\frac{1}{3} \pi r^{2} h[/tex]
= [tex]\frac{1}{3} *3.14 *3^{2}* 3[/tex]
=[tex]3.14*9[/tex]
=28.26 [tex]inch^{3}[/tex]
Now there are total 15 guests, Each of get
=[tex]\frac{28.26}{15}[/tex]
= 1.884[tex]inch^{3}[/tex]
3.Volume of round cake (d= 8 inch, r=4inch, h= 3 inch)
Volume= [tex]\frac{1}{3} \pi r^{2} h[/tex]
= [tex]\frac{1}{3} *3.14 *4^{2}* 3[/tex]
=[tex]3.14*16[/tex]
=50.24 [tex]inch^{3}[/tex]
Now there are total 15 guests, Each of get
=[tex]\frac{50.24}{15}[/tex]
= 3.349 [tex]inch^{3}[/tex]
4. Volume = l x b x h
= 6 x 9 x 2
=108 [tex]inch^{3}[/tex]
Now there are total 15 guests, Each of get
=[tex]\frac{108}{15}[/tex]
= 7.2[tex]inch^{3}[/tex]
According to question each person may get 8 [tex]inch^{3}[/tex].
Only the square cake can be distributed in such a way that each person may get 8 [tex]inch^{3}[/tex], with the least amount left over .
